The electron shell is also called the principle energy level in chemistry and atomic physics. The shells starting closest to the nucleus names go from shell 1 or shell K, shell 2 or shell L,shell 3 or shell m, etc. Each shell contains a certain amount of electrons the first shell starts with two and the number increases for each shell.
The negatively charged particles of an atom are in an outer shell.
The electron configuration of argon is [Ne] 3s2 3p6. From this, we can see that the outer shell contains eight electrons.
Copper is a non metal element. There are 29 electrons in a single atom.
Inner shell electrons are electrons that are located closer to the nucleus of an atom, shielded by outer electron shells. They have lower energy levels compared to outer shell electrons and are generally not involved in chemical reactions.
the first ring has two second has ten and third has eight
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
no it only has 1 electron in the outer shell
These are the valence electrons.
Valence Electrons
The outer shell is called the valence shell
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
I believe it's just the outer shell. It is where the outer electrons are contained.
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
Alkali metals have 1 electron in their outer shell.
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
There is one electron on cobalts outer shell.
Sodium has one electron in its outer shell, so it tends to lose that electron to achieve a full outer shell. This makes sodium more stable as it follows the octet rule by having a complete outer electron shell with eight electrons.
